Getting closer to the real thing

Back from my week off, good times. Big difference between Abisko with over a meter of snow and Lund with almost summer weather.

Begun implementing face warping filters this week to make happy/sad/whatever faces on people. Quite cool. Also started looking at the report and presentation and all the things around that.

Just now I'm traveling by train to Abisko for a weekend of snow and heliski. Gonna be nice with some time off.

When I come back I'm gonna plan for new filters, make a midterm presentation for the department and attend an interview. Busy week :)

Some output ...

As promised I've now put some output from my work here. My fantastic super mega sketch-filter is applied on these images, first one is the original, second one with color blending and the last is the black and white version (no blending with original).






Not that fantastic, needs quite high resolution on input otherwise it will be very blurry because of the double 3x3 kernel filter pass. Still it's not that slow on a big image.

Next week will maybe bring a halftone filter and then an other attempt two strip Technicolor filter.

Weeks keep running...

So, week number seven has started and I thought it was time for an update. The weeks keep running and I feel that I've produced at least something, but not as much as I first thought I would.

I've been looking at HDR and Tone Mapping filters the last weeks, reading some papers and trying to implement a nice TM (Tone Mapper). Almost all papers included algorithms with nice result but none of them would be possible to implement on an cellphone because of the limited CPU. So, the best TM I implemented was the most trivial one... (pixelA + pixelB) / 2 :)
Ok, now I fine tuned the algo somewhat by adding support for non linear clipping of white values, but still very trivial. But I know a lot more of HDR and TM now.

The coming weeks are gonna be about sketch/line art filters.

Stay tuned!
